Mark these as failing on sparc instead of sparcv9.
The configure script no longer tells us that we're configuring for SparcV9
specifically.
2004-06-17-UnorderedCompares may work on SparcV8, but it's experiental
anyway.
2005-02-20-AggregateSAVEEXPR should fail on any Solaris machine, as Solaris
doesn't provide complex number support.

One +record is printed per line; fields are separated by spaces.
